See instructions for valve body identification guide.

Sonnax Zip Kit U660E-ZIP targets the root cause of multiple complaints by sealing the critical circuit pressure losses in the Toyota/Lexus U660E and U660F valve bodies. The kit contains uniquely designed parts to prevent the loss of pressures within the main line, clutch apply control and lockup control circuits. The kit also seals multiple circuits known to suffer from end plug leakage or poor checkball sealing. No special tools are required for installing these parts.

The Zip Kit quick guide provides clear and easy instructions on one sheet to get the unit sealed up and back on the road fast. In addition to general rebuilding tips and technical information, the technical booklet included in this kit contains vacuum testing information and locations at other key areas of the valve body.

Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.

Installed this kit on my 2007 Camry 3.5L. Although it has 158,000 miles it runs great! Obviously shift feel has always been an issue with this trans and this kit does the job. I also like the fact that it doesn't require drilling in the VB castings. No improvement required to this kit. Keep up the great work!
